Battery Venting
I have a truck camper. The battery box inside the unit is the standard box with vents in the lid to intake air and a vent on top of the lid with a tube going to the outside of the camper. My conce...

Short of forced air, I would not make such an assumption.. HOWEVER I can answer your question.. Density.
Now.. Fact is I do not know the numbers.. but I know that normally one of those vents is placed higher than the other... Air by itself will have a DENSITY that is different than air laden with battery fumes,,, I will not speculate as to if that density is higher or lower but the more dense air will naturally move down and the less dense air will naturally move to the top. this is why hot air rises, it is less dense (not lighter as most folks say, a kilogram of air is still a kilogram of air, but a kilogram of HOT air is a lot larger at the same pressure than a KG of cold air).
So it is natural convection that powers the forced air vent.
